Feeling Faint? Drink Water

While politicians fight over how to reduce the cost of drugs, there's one

" medicine " that costs almost nothing and is as close as the nearest faucet:

water. At the annual meeting of the American Heart Association, held

recently in New Orleans, a group of investigators at Vanderbilt University

and at Humboldt University in Berlin presented findings that drinking tap

water before standing from a sitting or prone position prevents orthostatic

hypotension, or fainting, in patients with various kinds of autonomic

failure. Jens Jordan, of the Franz-Volhard Clinic at Humbolt University,

said that previous studies show that the mechanism of action involved in

preventing blood pressure drops after water consumption is not an increase

in plasma volume, but rather vasoconstriction. By interrupting the

sympathetic or autonomic nervous system in this way, the pressor response is

abolished, " so apparently, some patients have retained some response of the

autonomic nervous system, although they have autonomic failure, " said

Jordan. The average amount of water consumed during the study was 16 ounces,

although there was a dose-response curve and the remedy did not work in

every patient. Jordan said that drinking water also helps patients with

autonomic failure after meals, when they are likely to suffer a sudden drop

in blood pressure. By drinking the water before they stand up, Jordan notes

that patients " have a pretty large increase in blood pressure, and this

occurs very rapidly--within 10 minutes. It reaches its maximum after 30

minutes, which is better than most medications we used in these patients. "

Jordan hypothesized that patients with conditions other than autonomic

failure, such as multiple system atrophy or orthostatic intolerance, might

also benefit from water consumption before standing. Patients affected by

orthostatic intolerance are usually between 20 and 40 years of age, and

Jordan estimates there are probably 500,000 to a million such individuals in

the United States. Also, water drinking may well help patients who have been

hospitalized, or others lying in bed for a long time, to prevent fainting

when they stand.

1 litre = 35 oz

Does that help?

Timo,

Is that a trick question???? Cubic centimeters (cc) is a measure of volume and

ounce is a measure of weight for the most part. If you are looking at a liquid

(or fluid) ounce then one ounce equals 29.573 millilitres.

Take care, Bill Werre
